They say you shouldn't bite the hand that feeds you. But at this rate, the producers of Two and a Half Men will have no fingers left.

The career of the CBS sitcom's half-man, Angus T. Jones, is in serious jeopardy this week after he recorded a video testimonial for a Christian website in which he called the show "filth" and begged people not to watch it.

"If you watch Two and a Half Men, please stop watching Two and a Half Men," Jones, 19, says in the now-viral video interview for the Forerunner Chronicles website, part of which was recorded in his trailer on the Warner Bros. lot where the series is filmed.

"Please stop watching it. Please stop filling your head with filth," Jones pleads in the video. Later, he adds, "You cannot be a true, God-fearing person and be on a television show like that. I know I can't. I'm not OK with what the Bible says and being on that television show."

Jones joins former co-star Charlie Sheen in committing job suicide on Two and a Half Men, although the two actors couldn't be more dissimilar. But it's rare for stars to disparage a show or film while still working on it - usually that's done once the show is wrapped and the actor can safely take potshots from a distance.

Here are some of our favourite instances of stars slagging their work, and how they rate on the Sheen-o-Meter of career-impairing outbursts.

Charlie Sheen on Two and a Half Men producer Chuck Lorre

"He's a stupid, stupid little man and a p---y punk that I'd never want to be like. That's me being polite."

"First of all I want to thank Warner Bros. Thank you for putting me in a piece of s--- god-awful movie... I was at the top, and then Catwoman plummeted me to the bottom."

Sheen-o-Meter score: 1 out 5. 'Cause she was playing along and being funny about it.

Megan Fox on Transformers and working with Michael Bay, whom she compared to Hitler

"It's my first real movie, and it's not honest and not realistic... but unless you're a seasoned veteran, working with Michael Bay is not about an acting experience."

Sheen-o-Meter score: 4 out 5. What's she done since that anyone cares about?

Brad Pitt on The Devil's Own, directed by Alan J. Pakula, who died the following year

"The most irresponsible bit of filmmaking, if you can even call it that, that I've ever seen. I couldn't believe it."

Sheen-o-Meter score: 3 out 5. Slagging his own movie doesn't seem to have hurt his career.

Mandy Patinkin on Criminal Minds, which he quit after two seasons

"The biggest public mistake I ever made... I thought it was something very different. I never thought they were going to kill and rape all these women every night, every day, week after week, year after year."

Sheen-o-Meter score: 4 out 5. A procedural crime drama about crime? I quit!

Alec Guinness on Star Wars, which he came to from a career of mostly serious roles

"Apart from the money, I regret having embarked on the film. I like them well enough, but it's not an acting job, the dialogue - which is lamentable - keeps being changed and only slightly improved."

Sheen-o-Meter score: 3 out 5. Crotchety complaints, but with merit.

David Duchovny on The X-Files, and how he was disappointed with the series' ending

"This isn't a resolution for my character. We're resolving things that had nothing to do with Mulder. I felt like it was a lost opportunity."

Sheen-o-Meter score: 2 out 5. We're still hoping for another X-Files movie.

Sylvester Stallone on Stop! Or My Mom Will Shoot, his 1992 "comedy"

"If you ever want someone to confess to murder, just make him or her sit through that film. They will confess to anything after 15 minutes."

Sheen-o-Meter score: 1 out 5. Sly's just trying to help the criminal justice system.
